Envelope



Patented Dec. 18, 1934 UNITED STATES PATENT OFFICE Application October 10,

ZOlaims.

This invention relates generally to envelopes,

and particularly to that class of envelopes having means for supporting same in suspension from a support.

The main object of this invention is the construction of an envelope having a single opening formed in the structure thereof, which opening is confined to the fiap portion.

The second object is to provide an envelope with or without a transparency and capable of being sealed along its entire length and capable of being suspended from a milk bottle, door knob or other projection, and at the same time affording protection to the envelope seal and the sides of the envelope by draining moisture toward the ends of the envelope.

The third object is to construct an envelope whose flap is provided with an enlarged circular opening, which opening can receive the neck of an ordinary milk bottle.

The fourth object is to provide the flap perforation with an inwardly extending tab constituting a latch for holding the envelope in position on the milk bottle.

These, and other objects, will become more apparent from the specification following, as illustrated in the accompanying drawing, in which:

Fig. 1 is a front elevation of the envelope.

Fig. 2 is a side elevation of the envelope.

Fig. 3 is a front elevation of the envelope showing same sealed.

Fig. 4 is an end elevation of the sealed envelope showing same suspended from a door knob.

' Fig. 5 is a front elevation of the envelope showing same being supported by a milk bottle.

Fig. 6 is a side elevation of the envelope and bottle of Fig. 5.

Similar numbers of reference refer to similar parts throughout the several views.

Referring in detail to the drawing, there is shown in this instance an envelope having a front 10 provided with a transparency 11 and a back 12 whose lateral wings 13 are secured to the edges of the front 10. The envelope is provided with a combined closing flap 14 which is coated with adhesive and a supporting flap 15. The supporting flap 15 is provided with a circular opening 16 into which extends a retaining tab 17. The

0 particular form of the exterior edge 18 of the flap 15 is of minor importance.- It is desirable, however, to provide a crease 19 between the flap portions 14 and 15 which, when the flap 15 is folded, forms a gutter 20 by means of which moisture is carried to the ends of the envelope and prevented from running down either the front or back thereof.

It will be understood. of course, that the transparency 11 may be on either the front or the back or may be dispensed with altogether with- 1932, Serial No. 637,115

out departing from the spirit of this invention.

The operation of the device is as follows: Assuming that the contents of the envelope having been sealed therein and the flap 15 been folded back by creasing same along the line 19, the device may be either suspended from a door knob 21, as shown in Fig. 4, or from a milk bottle, as shown in Fig. 6.

It will be noted that when suspended from a milk bottle 22 that the tab 17 is below the mouth 23 and serves to prevent the accidental removal of the envelope from the milk bottle. It will also be observed that an envelope of this nature lends itself admirably to advertising purposes and overcomes the objections usually ofiered to other forms of envelopes in which the perforation not only extends through the flap but through the body of the envelope, requiring therefor the employment of an oversized envelope at a necessarily greater cost.

Furthermore, when the opening passes through the body of the envelope, it ceases to be waterproof. In fact, the opening becomes a collector for moisture which then finds its way inside the envelope from which it cannot escape.

It will be understood that in view of the fact that these envelopes may be exposed to rain and snow it is desirable to make same out of material adapted to resist moisture, such as waxed paper or similar substance.

I am aware that numerous forms of envelopes have been constructed in the past, in which the body of the envelope is perforated. It is not my intention to cover such devices, but only such envelopes as are described in the following claims.

I claim:

1. An envelope having a closing flap provided with adhesive, adjacent to the open side of the envelope, and having the tip of the flap folded back beyond the end of the envelope, when sealed, said fold forming a gutter for drainage purposes extending substantially the full length of the envelope, the extended portion of said flap having an enlarged opening for receiving the neck of a milk bottle from which said envelope may be suspended.

2. An envelope having an elongated flap forming a closure therefor, the tip of said flap being folded backwardly upon itself in a manner to extend beyond the uppermost edge of the envelope, the extending portion of said flap having an enlarged opening therein adapted to encircle the neck of a milk bottle from which said envelope may be hung with its flap uppermost, said flap' opening having a projection extending part way into same from the side nearest the envelope adapted to serve as a latch on the under-side of a milk bottle lip.
